Coen brothers thriller No Country For Old Men has won two more prizes as the awards season enters its final week.
No Country For Old Men is up for eight Academy Awards
The film, favourite to win best picture at the Oscars this weekend, won sound mixing's top prize at this year's Cinema Audio Society awards.
Joel and Ethan Coen's drama has also been named best contemporary film at the annual Art Directors Guild awards.
Academy members have only a few hours to return their final Oscar ballots in order for them to be counted.
Any received by accounting firm PricewaterhouseCoopers after 1700 PST on 19 February will not be included in the final tally.
No Country's sound mixing award was accepted on Saturday by production mixer Peter Kurland and re-recording mixers Skip Lievsay, Craig Berkey and Gregg Orloff.
On the same day, production designer Jess Gonchor accepted his accolade for the film's art direction from the Art Directors Guild.
The guild's award for best period film went to oil prospecting drama There Will Be Blood, while The Golden Compass won the fantasy film prize.
Sunday, meanwhile, saw the American Cinema Editors Awards - known as the Eddies - give prizes to action thriller The Bourne Ultimatum and Tim Burton musical Sweeney Todd.
